Transformers and Their Hidden Risks

The recent power outage at Heathrow Airport has highlighted a critical issue affecting airports, logistics hubs, and crucial infrastructure across the globe: the outdated transformers that are operating without real-time monitoring. This incident serves as a wake-up call that underscores the potential systemic risks lurking beneath the surface.

The Incident’s Aftermath

Causing the cancellation of over 100 flights and severely disrupting cargo operations at one of the world’s busiest international airports, the event has brought a renewed focus on the reliability of electrical grids. It has been noted by industry experts that power outages such as the one at Heathrow are not merely unfortunate accidents; they are, rather, foreseeable failures that could be mitigated with better monitoring systems.

Aging Assets Bring Increased Risk

According to insights from key industry players, many transformers in both the UK and US date back over 40 to 50 years. As these assets age, the risk of internal failure increases significantly. David Meyers, CEO of H2Scan, points out that operating without continuous monitoring is akin to “flying blind”—a situation that can lead to catastrophic consequences.

The Ripple Effect on Cargo Operations

In the fast-paced world of airfreight and logistics, energy reliability is often taken for granted—until it’s snatched away. Just one transformer failure can cause a domino effect, disrupting everything from loading and scanning to refrigeration and security systems. Unfortunately, the condition of the transformers isn’t examined closely until something goes wrong.

Current Monitoring Practices

Traditionally, transformer monitoring has relied on periodic oil sampling, which can occur every six to 48 months. These samples are sent to laboratories to check for dissolved gases that indicate faults such as overheating or arcing. However, serious issues can develop between these scheduled checks. Meyers creatively likens this to only getting your blood pressure checked once a year while being at high risk for heart disease.

Hydrogen: A Vital Indicator

Hydrogen is an early warning sign of trouble within transformers, often released weeks or even months before an actual failure occurs. Real-time monitoring of hydrogen levels can thus provide advance notice of potential problems.

Implicații economice

The fire at Heathrow was reportedly ignited by an unidentified transformer fault at a substation linked to the airport’s air traffic control systems. Investigations into this incident reveal that the economic toll is significant, with industry analysts estimating losses to exceed £100 million—a staggering £6 to £7 million per hour in lost passenger and cargo revenue.

For reference, downtime costs at other industrial locations can hit around half a million dollars an hour; for an airport, these figures can be exponentially higher.

Beyond Financial Losses

In addition to economic ramifications, transformer failures come with safety, environmental, and regulatory concerns. Leaking oil from failed transformers near water bodies can trigger expensive clean-up operations. Hospitals, data centers, and cold-chain warehouses are particularly vulnerable as temperature fluctuations increase the demand on older assets.

The Shift Towards Continuous Monitoring

Until recently, continuous monitoring was a privilege mostly extended to critical transformers. However, new advancements are making continuous monitoring accessible at a fraction of the previous cost. The installation of hydrogen sensors can now be executed swiftly, in under two hours, and without needing the transformer offline, enabling rapid retrofitting of aging units.

Insurance Companies Taking the Lead

As the technology becomes more available and cost-effective, insurance providers are recognizing its value. They are starting to offer reduced premiums for monitored equipment—a significant incentive for businesses to adopt better monitoring practices.

The Role of International Standards

Organizations like IEEE and CIGRÉ are currently working on new guidelines that incorporate monitoring requirements. Fire safety organizations are also emphasizing the need for improved diagnostics to prevent electrical fires.

Strategic Prioritization is Key

While the transformation in monitoring is not yet universal, there are signs that a change is on the horizon. As emphasized by Meyers, it’s unrealistic to retrofit every transformer immediately; therefore, focusing on the most critical assets tied to passenger operations, cold-chain cargo, or air traffic systems is crucial.

Real-World Examples of Monitoring Success

Citing various cases, Meyers illustrates how monitoring hydrogen levels has prevented transformer failures. In one instance, rising hydrogen levels led engineers to uncover a loose connection inside a major transformer, which could have resulted in fire or outage had it gone undetected. In another case, operators used monitoring data to recognize temporary faults, averting unnecessary and costly interventions.

This shift toward understanding asset behavior enables operators to avoid false alarms, prioritize maintenance efforts, and ultimately extend the life of their equipment—bringing about a win-win scenario for everyone involved.

Looking Ahead: AI and Machine Learning

Incorporating AI and machine learning into these practices may further refine the accuracy of predictive modeling, allowing organizations to utilize real-time data for future failure forecasts.

Importance in Logistics

With airports transforming into logistics hubs—handling everything from e-commerce to perishables and pharmaceuticals—the need for reliable electrical infrastructure has never been more critical. As electrification increases, especially in ground operations and cargo handling, maintaining grid stability through effective monitoring will be paramount to sustaining operational continuity.

Indeed, monitoring transformers has evolved from being merely an engineering concern to becoming integral to business continuity strategies, fire safety measures, and environmental obligations.

Concluzie

In summary, ageing transformers represent a latent risk that has far-reaching implications for logistic operations. From the economic burden of outages to potential safety and environmental hazards, the importance of continuous monitoring cannot be overstated.
